'REFRIGERATING SHIPPING-CASE.

Specification of Letters Patent.

Patented Dec. 2,1913.

To all whom it may concern Be it known that I, ARTHUR P. HAINES, a citizen of the United States, residing at Rockland, county of Knox, State of Maine, have invented certain new and useful. Improvements in Refrigerating Shipping- Cases, of which. the following is a specification.

This invention relates to shipping packages and particularly to packages for the shipment of perishable articles of food, such as fish and like food which must be kept cool during transit.

In handling many of these perishable articles which are packed in ice, it has been found difficult to prevent them from being mutilated by contact with the sharp corners and edges of the broken ice. Such mutilation detracts materially from the market value of the articles before reaching their destination.

It is the object of my present invention to provideashipping package in which completeness of cooling is obtained and yet the fish and other articles are protected against being cut by the shifting of the ice.

The construction and use of my device will be more fully described in the specification which follows.

In the drawings which form a part of the specification I have shown a shipping package which has been found to fulfil the requirements of practical use and which is capable of economical and satisfactory construction.

Throughout the specification and drawings like reference numerals are employed to indicate corresponding parts.

In the drawings :Figure 1 is a central vertical section of a package in accordance with my invention, and Fig. 2 is a transverse central section of the same.

My shipping case consists of a container 1 which may be of any suitable construction, such as that of a barrel, cask or tub and suitably strengthened as by hoops 4.

Through the bottom 2 of the container 1 I form a suitable drain opening 2 and within the container fasten transverse strips 5, 5 which bear against the sides and preferably define an inner space substantially triangular in cross section. To these strips are nailed uprights 6 leaving between the grid thus formed and the sides 1 of the container a space within which a filling of broken ice 9 may be packed.

About half way up the grid formed by the strips 6 I nail cleats 8 on which a circular platform 8 can be rested and upon the tops of the strips 5 a larger disk or inner head 7 is rested. The strips 5 are spaced a sufiicient distance below the top of the container 1 to permit a suitable packing 10 of broken ice and on top of this is a suitable covering 3 preferably of coarse matting or the like.

The fish or other goods to be shipped are packed by first filling the bottom of the container below the cleats 8 The inner partition 8 is then placed in position on the cleats 8 and a second packing is filled above it. The ice packs 9 are then filled in outside of the slatting 6 and the inner head 7 is then put in place. The ice pack 10 is then laid on top of the head 7 and the covering 3 drawn over the top of the container. In this manner I am able to prevent the mutilation of the contents of the package and prevent the ice packs from shifting or moving about as the container is handled in transit. I, furthermore, prevent the contents from being too closely packed or squeezed in the bottom of the container by means of the intermediate supporting partition 8. This permits the outer packs of ice to keep the entire contents cooled through as well as to avoid the excessive pressure of the upper layers of contents upon the lower layers of contents.

Various modifications may obviously be made in the construction and material of the container and in the proportion and detail of the parts, all without departing from the spirit of my invention if within the limits of the appended claim.

What I, therefore, claim and desire to secure by Letters Patent is:

A refrigerating shipping case comprising an outer container, a plurality of symmetrically disposed grids therein, and forming between their outer faces and the inner face of the container wall ice containing pockets spaced from each other by intervenin parts of the container wall, said grids aIso defining between their respective inner faces pockets, constituting an ice support and a and those areas of the container Wall which cover above said ice support. 13 space the grids from each other a contain- In testimony whereof I affix my signature ing space adapted to receive the articles to in presence of two Witnesses.
